Usage of Wantong Weeding Cloth
1. The laying of grass proof cloth is also very simple. Generally, the ground can be tamped first. After the whole roll of grass proof cloth is spread and leveled in the required direction, an iron hook can be driven into the ground to fix it at a certain distance at the joint. When building the greenhouse, first pave the grass proof cloth, and then build the greenhouse.
2. During the laying of grass proof cloth, there should be a certain overlap in the width direction, and the overlap length should not be less than 10 cm or 20 cm. When indoor lapping, it can be placed naturally, while outdoor lapping adopts some additional fixing measures.
3. Construction of grass proof cloth laying cushion: in order to make the floor cloth permeable, well ventilated, flat and with certain surface strength, the grass proof cloth laying base course shall be treated.
4. Generally, a coarse sand layer of about 10 cm should be laid under the grass proof cloth. Because the coarse sand has the characteristics of solid aggregate structure, large pores, small deformation under external force, etc., it is very suitable for the surface cushion of the ground cloth.
5. For the lower part of coarse sand, the treatment method shall be determined according to the local soil conditions. Generally, if the soil is solid and has good water permeability, a coarse sand layer can be directly laid on the surface. Otherwise, a gravel layer or a pebble layer of 10 to 15 cm should be laid under the coarse sand to ensure the water permeability of the base course and the strength of the surface of the ground cloth, which is conducive to the placement of crops and the walking of workers.
6. The color of grass proof cloth is usually selected. Black grass proof cloth can be used indoors or outdoors, while white grass proof cloth is mainly used indoors. When the white grass proof cloth is selected in the greenhouse, in addition to the general functions of the grass proof cloth, the white grass proof cloth also has some auxiliary functions.
